` Tlleisclhedule referir-er1'V to in these LettersPatent and making part of the same county, and State of NewYork, have invented a new and useful Improvement'iu,Gas-Regulators; andl do hereby declare-the following to be afnll, clear, and

exact description thereof, which will enable those skilled A `inthe art to make and use theV same, reference beingA g had ltotheaecompanying drawing forming. partof `this speci'ficatiomin which drawing- Figure 1 represents a central sectionf'of this invention.- l

4Figure 2 is a plan or 4top view of the same.`

Figure 3 is acentral section of th'e valve detached,

`showing thesame as,4 it appears when in' operation. Similar letters indicate corresponding parts.

'This invention consistsin acup-shaped valve vfitting into a nozzle, which' is provided with a shouldenvto receive the bottouredge of-said valve, while the valve v is provided with aprojecting-i'im, to rest in the top edge ofthe nozzle, both the valve and nozzle being perforated with holes', and inclosed in a globe-shaped chamber, in such varnanner that, when the valve is i clear down, tlreholes are all '-closed, and the' contact of 'saidyalve with theshoulder, and with the top'edge of -the'nozzle prevents thc"pa'ssage of any more gas @than required tobalan'ce thepressureou `thevalve from `ahove-` aud below; 'but as. soon as, 'onev or more burners aretrued on, (whereby the pressnreon the `topof the valve is diminished,)}the valve is raised,

andl the required quantity ot` gas is allowed to pass through the holes in the nozzle and in the valve, and

`by the action of .the `valve, the, quantity of gas admitted to the burners is equalized, an'dga uniform and steadyl light vis, obtained.

. A perforated screen exteudiugaover the valve pro,-v tects said valve against impurities', and prevents it 1 `from rising beyond the desircdheight, Y

In the drawing-7 'lheletter A designates anglobe-shaped` chamber,

v which "is providedwith aniinterualI s crew-thread,'a, to

receive `the nozzle B. C

'lliisznozzle provided at` its bottomn'itha screw` thread, b, to be applied to the gas-meter, or to a pipe connecting with said meter, and another' pipe attached tothe upper end of the chamber A, leads to the burners. i The nozzleB is. bored ont to recei-ve thek cup-shaped valve O, and-it is provided'with an internal shoulder, c, for the valve to rest upon, while said valve is furnished'with a projecting rim, 1,-whiel1 bearson the top edge of the nozzle, when-the valve is clear down. In the sides ofthe nozzle is a-series of holes, c, and a similar. set of l'loles",f, is. madein the sides of thenntil the valve is raised a certaindistance from its seat c. i

By this arran ement, a uniform and steady lightis produced, and a lwaste of gas is obviated.

What VI claim as new, and desire to secureby. Letters Pateut,ris y l. The arrangement of a cup-shaped valve fitting into a nozzle, which is provided with a shoulder to receive therbottoxn edge'of said valve, while the' valve is.

provided with aprojectihg rim, to rest on .the topedge of the nozzle, both the valve and the nozzle being perforated with holes, substantially in the manner herein shown-and described.

2. The arrangement of a perforated screen, in com bination with 'the cup-shaped valve aud-nozzle, con-V structed and operating-asset-forth.
